AIM: We estimated the relationship between routine biochemical laboratory parameters with static bone histomorphometric parameters and their high and low bone turnover capacity predictability in hemodialysis patients.
METHOD: It was a single-center cross-sectional study, included 28 hemodialysis patients. The routine biochemical parameters measured including calcium, phosphorous, alkaline phosphatase, intact PTH, and 25-hydroxycholecalciferol. The histomorphometric parameters assessed were osteoblasts perimeter, osteoclast perimeter, eroded perimeter, osteoid perimeter, bone fibrosis and bone volume.
RESULT: Total 28 hemodialysis patients underwent bone biopsy. Seventy percent were male, with a mean age was 33.07±10.42 yrs; serum alkaline phosphatase was 219.10±311.3IU/ml; vitamin D was 18.18±9.56ng/ml, and intact PTH was 650.7±466.0pg/ml. Intact PTH had a significant positive association with osteoblast, osteoclast, eroded surface, and osteoid perimeter. Serum alkaline phosphatase had a significant relationship with bone fibrosis (r=0.525, p-value=0.004). Intact PTH was significantly higher in females than males (1078.75±533.04 vs. 479.6±309.83; p-value=0.004). The osteoid surface was significantly high in females compared to males (p=0.038). Age had a significant impact on osteoblast and eroded surface (p=0.008 and p=0.031, respectively). Intact PTH is a reliable biomarkers for bone turnover compare to ALP (p<0.001 and p=0.554, respectively).
CONCLUSION: Intact PTH strongly associated with bone formation, bone resorption parameters. Gender and age had significant impact on static histomorphometric parameters in our study.
